Opinions on KN air filters vs other filters? I like my KN,but oiling gets to be a pain-any other opinions on air filters-I live on Mex border and drive in lots of Moon dust

Welcome gebbrown, for a drop in OEM replacement, I would recommend the Amsiol Ea (dry) filter incorporated with the nanofiber filtration media. It also has a recommended service life of 100,000 miles or four years. Out performs cellulose and wet gauze filters. Or if your using a conical induction type, Amsoil also has the EaAU induction filter with the nanofiber media. Also available are the New Amsoil pre-filters for the EaAU induction filters. The filters are re-usable, when dirty you can use light air pressure to blow out to clean. Here are some links below:

Amsoil also provides EaPF Pre-Filters (http://www.amsoil.com/StoreFront/eapf.aspx)
What Are Pre-Filters?
Ea Pre-Filters fit over the top of existing air filters. These polyester mesh bags feature an industrial grade elastic band at the opening to ensure the pre-filter does not slide off.

Why Use Pre-Filters?
Racers and off-road enthusiasts subject their vehicles to some of the most severe conditions possible. These vehicles operate in areas of heavy dirt and mud that gets slung into every crack and corner, often clogging air filters. AMSOIL Ea Pre-Filters are designed to keep larger particles from getting into and clogging the pleats of air filters. When an air filter is clogged, the engine loses horsepower and, in the case of Ea Air Filters, the filter must be cleaned. There is no vacuum or compressed air available on the race track or out in the swamp, but an Ea Pre-Filter is easily removed and shaken free of debris in seconds.

If you are running an oiled gauze filter, reach into the intake tube with a clean white cloth and wipe the tube to find out what is getting through the filter. Amsoil claims that the Ea filters will trap 50 times as much dust as oiled gauze. My experience with them is that they definitely trap dirt, and lots of it. If you are running an enclosed OEM type filter you probably can clean it every 25,000 miles as recommended unless you are using your truck in extremely dusty conditions, then you might need to clean it more often. If you have an aftermarket intake with an open to air filter and put an Amsoil EaAU Universal element on it you will probably need to clean it every 5,000 to 10,000 miles, less often if you use a Pre-filter on it. One of my customers and friends clogged his EaAU3590 on his 7.3 Ford in about 6,000 miles, no pre-filter installed, and collapsed it while towiing his 45 foot 5th wheel Toy-Hauler. At first he was very unhappy about finding out that he needed to clean it so much more often, but he has now changed his tune after realizing how much dirt had been getting into his engine thru the gauze filter before. That, and the fact that it is so much easier to clean. We found thru this experience, and with the cooperation of Amsoil Tech when they tested this filter, that the best way to clean them thoroughly was by first blowing them from the inside and then vacuuming them with a shop-vac and brush. My own 7.3 has an EaAU-6080 mounted on an Air-Raid Intake. I cleaned it recently when I was prepping for a trip and found my Vacuum-Minder Gauge at approx half-scale with about 6,700 miles on it.
